Indonesia is a developing country that has great potential
to produce Waste energy. One of Waste energy that is produced
in Indonesia is the exhaust gas. With the great potential to
produce Waste energy Waste Heat Recovery system are the best
solution to recover Waste energy such as exhaust gas.
In this final project I designed a Compact Heat Exchanger
Louvered Fin Flat Tube using reference data from the actual
journals customized for laboratory scale experiments.
Furthermore Performance of Compact Heat Exchangers will be
tested by giving three exhaust gas flowrate variations high speed
0.4 ms medium 0.3 ms and low 0.2 ms. The working principle
of compact heat exchanger is to absorbs the heat energy which is
passed through a flat tube and louvered fins the heat energy
generated simulated by using a burner and the inlet exhaust gas
temperatur approximately 275 oC.
The results obtained from this experimental study are the
dimension of the compact heat exchanger LxWxH 300x400x12
mm air-side heat transfer maximum 3786 kW the water-side
heat transfer are constant at 3095 kW maximum Effectiveness
0.549 maximum NTU 1.004 overalls heat transfer coefficient
maximum 10303 Wm2.K the highest 916TLMTD 164.20 K.
